Alice Mic-Amp-Pak

Publish date:

What is it?An ultra-low noise microphone preamplifier. DetailsDesigned for use where long lines need to be driven or where conversion from mic level to line level is required, the Alice Mic-Amp-Pak is available in two versions: the single-channel Mic-Amp-Pak 1 and the dual-channel Mic-Amp-Pak 2. Both models feature switchable 48V phantom power and a switchable 80Hz high-pass filter plus front panel gain adjustment from 35dB to 75dB. Audio inputs and output are via Neutrik XLR connectors. Rack mountable (with the RPK-1 adaptor), the Mic-Amp-Pak offers a frequency response of 20Hz - 20kHz (+0dB/-0.5dB) and maximum THD of 0.009% (1kHz). Equivalent input noise is quoted at -131.3dB (150 ohm; 30Hz - 30kHz) and crosstalk is better than -90dB (at 1kHz). The balanced inputs are rated at 3k ohms impedance and maximum input level is -10dBu. The balanced and floating output provides an impedance of <1 ohm at a maximum output level of +26dBu.



Mic use moves to USB

Over the past few years many traditional microphone manufacturers have started to offer USB microphones, boasting designs and features aimed at the recording and broadcast market. Mike Hillier looks at what these new microphones have to offer.
